I have a problem in real.exe, I try to run wrf arw with the lateral and initial conditions of arpege0.1, at the beginning I had a problem in ungrib with Vtable, taking Vtable.ARW.UPP I succeeded in generate FILE **, geogrid **. nc and metgrid **. nc, I don't know if I made the right choice, but with real.exe I found problems and here is what it gives
--------------------------------------------------------------------------------------------

Thanks for sending those. The rsl files you sent were for your real.exe run (not wrf.exe); however, there is an error listed there:
Code:
-------------- FATAL CALLED ---------------
FATAL CALLED FROM FILE:  <stdin>  LINE:    1199
p_top_requested < grid%p_top possible from data

Your setting of 5000 for p_top_requested is standard, so I believe the problem is your "num_metgrid_levels" setting, which is only set to 1. What type of input data are you using? There should be many more levels than 1 (for e.g., GFS data have 34 levels).

Another problem I see is you have num_metgrid_soil_levels = 0. You must have soil temperature and moisture data in your input data. If you need information about obtaining input data, and the mandatory requirements, see this presentation.
